와, 멤버 변수 변경이 이렇게 깔끔하게 될 수 있다니...
C++ 진짜 멋지다!
C++ 진짜 멋지다! template operator=() 가 있어서 가능했다.

■ template<typename TDataChain, int TInIndexNo> class ZtCTypeByNo
ZtCTypeChain, ZtCObjtChain 등을 template 인자로 받아, 어떤 index
숫자로부터 type 을 알 수 있게 한다. index 는 0 부터 시작한다.
이러면 ZtCObjtChain 의 활용성이 점점 높어지는 것이다. -- 2025-10-23 19:47
